Abstract

Multi-wavelength imaging pyrometer (M-WIP) is presented for remote sensing of temperature profiles of targets with unknown emissivity. Fast algorithm and software package were developed for calibration and real-time M-WIP measurements. Experimental 7- filter line-sensing M-WIP system was implemented with 320 × 122-element PtSi IR-CCD imager. The M-WIP system was calibrated against a commercial blackbody source over temperature range from 450°C to 900°C. Signal processing included background subtraction and compensation for variation of dark current with detected signal and signal off-set sue to apparent BCCD trapping effect. Initial M-WIP measurement demonstrated temperature resolution ΔT of ±1°C for blackbody target over temperature range from 600°C to 900°C.
